The leaders of South Korea, the U.S. and Japan are meeting on the sidelines of the Nuclear Security Summit in The Hague on Tuesday.
The Washington-led summit will largely focus on the trilateral efforts to denuclearize North Korea.
There is a question of whether the three members of the six-party nuclear talks will be able to find a way to restart the multilateral dialogue that has been stalled since late 2008.
Seoul, Washington and Tokyo demand a sincere commitment from Pyongyang to fulfill its previous disarmament pledges.
Pyongyang and its main ally Beijing want an immediate return to talks.
China and the U.S. clearly differed on the preconditions to and the timing of the six-way nation dialogue when Presidents Xi and Obama met in The Hague Monday.
Many are eyeing Tuesday's three-way talks, because they represent the first between President Park and Prime Minister Shinzo Abe amid strained ties over historical and territorial issues.
Although the most contentious issues, such as Japan's denials of its colonial-era atrocities and its claims to Korea-controlled Dokdo Island, are not on the agenda, there's speculation as to whether the two leaders will discuss them.
And Seoul is also paying close attention to Tokyo's sincerety over its historical wrongdoings.
In fact, an aide to the Japanese prime minister earlier this week contradicted Abe's reaffirmation to Japan's wartime sex slavery apology, saying it could be revised depending on the outcome of Tokyo's review.
In any case, some pundits say Tuesday's summit could offer a break to a prolonged impasse between Seoul and Tokyo.
